Why is it always easy to die if you raise your own goldfish?

The goldfish I bought back can not be raised for a week, and a large part of it is because I didn't choose it well. Generally, cheap fish is sold by merchants when they are brought back, and they are not raised. The fish go from the fishing ground to the store and then to your house, and there is no rest in the middle of the two bumps, and the water environment changes several times, and the stomach is very easy to spoil.

You can't blame the merchants, because if you spend energy on fixing the water for cheap fish, the cycle is long, and you will lose money.

How to choose, if you really want to raise, raise as expensive as possible, the average merchant is more than ten yuan a fish, it is worth spending some effort to decide. After all, the sales volume of this fish is smaller, and the sales cycle is long. And you can't get a dead one.

Don't be afraid to buy expensive and die, cheap fish have a greater chance of dying (except for grass gold).

Then look at the water in the fish tank, it is best to be slightly green water, do not have black, white, yellow, these colors are basically drugged, some merchants in order to ensure that the fish do not die in the sales cycle, will be drugged, the fish are dependent on this medicine to continue life, as soon as you take it back, there is no medicine, you will die.

Finally, look at the fish, a fish tank is densely packed with fish, it is best not to touch, look at the density is relatively small, and then the state of the fish is very good to judge, don't be stunned, don't keep floating on the water, don't keep sinking. Look carefully for injuries. If you are familiar with the shop owner, you can ask to feed a few grains of fish food to try (this is used with caution, 90% of the boss will not agree, unless you buy hundreds of them) do not feed more, a few grains can, because you have to pick the fish that ate the fish food, the fish is best on an empty stomach during transportation, so you can't feed more, even if you don't feed, you can also see that because the fish is raised, the boss will usually feed, this time you walk over and put your hand above the water, the fish will reflexively come to grab, that's right.

Of course, after picking the fish, there are still factors such as crossing the water, raising water, changing the water, feeding, and filtering after returning home. After picking the fish, you will save a lot of trouble.

It means that you may change the water more frequently, or you don't use an aerator, so he will die if he lacks oxygen, or your fish tank is small, but it is not good for you to raise more fish.

Pay attention to water quality, change water frequently, feed less and eat more, and do not feed. Fish should not be kept at high densities. Always have some fish medicine, such as oxytetracycline, yellow powder, etc.

The goldfish raised by yourself are more likely to die, which may be because they have not yet mastered the ways and means of raising goldfish.
